使用 XeLaTeX 时，Trimbox 不会显示整页浮动

我的标签如下（感谢David Carlisle：我如何才能动态地（使用宏）设置 PDF TrimBox 并使其独立于编译器？和David Purton 使用 PDFLaTeX 设置 BleedBox）

我使用XeLaTeX上面的方法可以正常工作并TrimBox在所有页面中都使用，但是当出现整页浮动时它就TrimBox消失了，请建议如何实现...但是使用时所有页面都可以正常工作PDFLaTeX...

答案1

抱歉，我不知道它为什么会消失，我也没时间看。如果你想在所有页面上使用相同的裁切框，你可以使用pdf: ~ put ~ @pages ~。或者你可以尝试新的 pdfmanagement：

\DocumentMetadata{}
\documentclass{article}

\usepackage{graphicx}
\ExplSyntaxOn
\pdfmanagement_add:nnn{Page}{Trimbox}{[8.50392~8.50392~532.91336~702.99211]}
% or
%\pdfmanagement_add:nnn{Pages}{Trimbox}{[8.50392~8.50392~532.91336~702.99211]}
\ExplSyntaxOff
\begin{document}


\section*{Test Document}
\clearpage Just another page \ldots

\newpage

\begin{figure}[p!]
\includegraphics{example-image-a}
\end{figure}

\end{document}

这适用于所有引擎。

答案2

这基本上与 Ulrike 的回答相同，只是我使用你的代码作为基础（并修复了 Ulrike 的回答中的 Trimbox→TrimBox 拼写错误）。

我建议您使用新pdfmanagement代码，它目前有效，并且从长远来看肯定会更加可靠。

经过我的测试，这三种引擎均有效：
